There probably has been pictures uploaded already comparing the two, but here are my pictures. I hope they help.
They were taken with a light directly above them. I think they're a good depiction of the differences between the two. Honestly, besides the 700 being a little more green, there isn't much to complain about. The glare on the 700 may be a problem for some people, but compared to the 505, they're not that different.
700 is a bit bulkier...
